Overview
GeoBasemap subsystem is an effective application for displaying the projection location of survey data in the geodetic coordinate system, which enables the user to visually analyze the data. It’s an essential component of project management. After a project is created and data are loaded, users can select, display, edit, or calculate the data in this subsystem. It works like a bridge to communicate with other subsystems of seismic data processing and interpretation(2D/3D).
Key Features of GeoBasemap
The GeoBasemap subsystem displays data needed in seismic data processing and seismic interpretation, including the following layer data:
Seismic survey grid data
Well location data
Traverse trace data
Horizon data
Fault data
Fault polygon data
Grid data
Contour data
2D intersection misties data
Scatter data
Fan sector data
Along-horizon attribute data
Boundary data
Trap data
Velocity spectrums data
Sample data
Slice data
Fracture data
Azimuthal data
Gravities data
Magnetics data
Electromagnetics data
Terrains data
The layers displayed in the basemap have the following common functions: display proportion control, basemap redrawing, zooming in/out and restoring,
etc.
The basemap can be used to perform interactive operations: select seismic line, generate traverse, set well set, create fault polygons, delete interpretation horizon and calculate intersection misties, area, and distance, etc.
The following workflow of basemap functions is listed for reference:

Start-up
Preparations
In order to operate based on the project, GeoBasemap requires an existing project with necessary data such as surveys, lines and wells, etc. to be displayed by the basemap.
Starting the Subsystem
Use the system command of Geoeast to start the main console. Select Structural Interpretation or Reservoir Prediction from the main console, and click Basemap to start GeoBasemap,
According to the data we selected, there will be different contents shown on
GeoBasemap.
When we select the project node and it is the first time to start GeoBasemap, all the surveys will be displayed; but if it’s not the first time, then restore the previous view.
When we select a survey data from the main console, the GeoBasemap will be started displaying the data of this survey.
Main Window
This section will introduce the organization mode, arrangement, menubar, toolbar, Data Explorer Tree, colormap, and status bar of the Basemap Main Window.
General Description
Starting GeoBasemap subsystem displays its main window, shown in Figure 4-1:
Figure4-1
Users can freely drag, select, and arrange the locations of the six constituent areas labeled in Figure 4-1:
Menubar
Toolbar

Data Explorer Tree
Status bar
Menubar
The menubar, at the top of the Basemap Main Window, consists of menu items and their pulldown menus, as shown in Figure 4-2:
Figure 4-2
Toolbar
The toolbar, initially located below the menubar, contains buttons for frequently used functions and is divided by vertical lines into three parts: file operation, graphic zoom control, and data selection. Users can customize the toolbar according to their own needs.
Data Explorer Tree
The Data Explorer Tree is on the left side of the Basemap Main Window, listing all basemap data in tree form. The tree has the same look and feel as the Windows Explorer. Each type of data is organized into folders and sub-folders as required, and the layers of each date type is put in these folders or sub-folders. We call each item in the Data Explorer Tree, both data type and layer, a Node. Basemap data types include wells, traverses, fault polygons, faults, horizons, survey grids, sample, strata attributes, scatters, grids, contours, misties, fan sector, boundaries, velocity spectrum, gravities, magnetics, electromagnetics, terrains, trap, slice, fracture, and azimuthal fracture, all of which are listed under the tab Layer (Figure 4-4). The extended information for all data types is listed under the Ex(Extend) heading on the right side of the tab Layer. 3D or 2D information is listed behind the survey. For example, if ‘3’ is shown on the right side of a survey name, that means this survey is a 3D survey.
Most basemap functions can be managed on the Data Explorer Tree. Users can select the data to be displayed in the basemap, arrange the data display order, define the data display attribute, and activate the current layer.
Colormap
The 256-color colormap, initially on the right side of the Basemap Main Window, allows users to define a relationship between colors and data values. Adjusting the correspondence between color and data value can facilitate data analysis. The system has default colormaps, but users can create custom colormaps to suit
preferences or data distribution needs.
The layers using colormap in basemap include horizons, grids, contours, misties, scatters and attributes, slice, sample, fracture, azimuthal fracture.
Color Adjusting Tool
Display the colormap bar in the Basemap Main Window. Select View → Views→ Colormap Bar in the Basemap Main Window to display colormap on the right side of the canvas. The Colormap Bar has a toggle button. The colormap will not be displayed when the toggle is swithed off.
All colored layers displayed in the basemap canvas have separate colormap information. The value range of the currently activated layer is displayed in the colormap on the right of the canvas. When the activated layer changes, the corresponding colormap will change accordingly.
Setting Colormap Range
A ColormapModeGlobe flag is available on each parameter interface of the data that uses colormap.
The colormap range is set as follows:
1、Display of single layer
When a single layer is displayed, the range of colormap is the value range of the data whether the ColormapModeGlobe flag on the parameter interface is selected or not.
When a single layer of colormap used in the basemap is displayed, the colormap range is spread between the maximum and minimum values of the displayed layers. The colors of the layer will correspond to the color structure of the colormap.
2、Display of multiple layers
When multiple layers of colormap used in the basemap are displayed:
The Globe range of colormap is the union set of value ranges of all color layers. The color parameter, value range, color spectrum saved by the activated layer are displayed in the colormap on the right of the canvas.
If the activated color layer mode ColormapModeGlobe is selected, the range of colormap is the Globe range or the value range of the current activated layer.
If the activated layer is not a color layer, the colormap range is spread between 0~100.
Changing Color Chip of Colormap
After the color chip or range of colormap is modified by double-clicking on
colormap in the popped-up colormap setting dialog, the basemap will update and activate the color of the layer based on the updated colormap.
Status bar
The status bar, at the bottom of the Basemap Main Window, shows the current work status, the function of the icon at which the mouse is located, layer information (such as activated layer name), geodetic coordinate, line/trace number (name), etc.
Data Explorer Tree Operation Instructions
Data organization, data type classification, display function, and display management of the Data Explorer Tree are introduced in this section.
Data Type and Attribute
Data that can be independently displayed in the Basemap Main Window belong to one of the following data types, detailed below.
Well data
Well data describe the well location, bottom hole location (deviated well), well trajectory (deviated well), and well top information. The display of well, bottom hole, and well trajectory is determined by the geodetic coordinates of the well. The display mode of the well and bottom hole is a point. The well trajectory is composed of projection lines on the base plane. The well top is composed of the geodetic coordinates and its attribute label.
2 Traverse trace
A traverse describes the location of any vertical section on the plane. The traverse can be formed in a single survey, multi-survey, or combined survey.
Fault polygon
A fault polygon on the basemap is the projection on the horizontal datum of the intersection of fault and horizon and might be upthrow and/or downthrow fault polygons. Fault polygons can be formed in multi-surveys or combined surveys.
Fault data
The plane location and fault point location of the fault segment can be displayed on the basemap.
Seismic horizon
Seismic horizon data, obtained from seismic section interpretation, are expressed by the line/trace locations and time/depth values. Horizon data reflect the structure of the interface in the survey area and can be interpolated to get the grid data of the horizon.
Survey grid data
Survey grid data, in (x, y) coordinates, define the plane locations of seismic lines. Surveys are divided into 2D and 3D survey grids.
Surface attribute data
Seismic attribute data are generated by the attribute analysis subsystem.
Scatter data
Scatter is defined by the plane location (x, y) and attributes values of the grid point. Scatter data can be displayed in scatter mode or in contour mode.
Grid Data
Grid data are obtained by interpolating control point data and are defined by the plane location (x, y) and an attribute value of the grid point.
Contour
Data variability can be expressed by contours. Contours can be either opened or closed, which is defined by the plane position and attribute values of the lines.
Fan sector data
Fan sector data display.
Misties data
Display horizon mistie data.
Boundary data
Display the boundary data generated by the mapping subsystem.
Trap data
Trap data is generated by the Geomapping subsystem based on the contour.
Velocity Spectrums
Stack velocity Spectrums.
Gravity data
Including scatter data and grid data of gravity data.
Magnetic data
Including scatter data and grid data of magnetic data.
Electromagnetic data
Including scatter data of electromagnet data.
Terrain data
Including scatter data and grid data of terrain data.
Slice data
Display slice data.
Specimens data
Display specimens data.
Fractures data
Display fractures data.
Azimuthal Fractures data
Display azimuthal fractures data.
Images
Display images.
The data type determines its display style on the basemap, but detailed descriptions of data components are defined by data attributes. The Data Explorer Tree addresses the attributes (display parameters) of the above data types separately.
Structure and Functions of the Data Explorer Tree
The Data Explorer Tree (Figure 5.2-1) expresses data display relationships, lists display data and controls layer display and display order. The Data Explorer Tree consists of a layer list and extended information about the layers.
The Layer consists of the following 2 levels: Data Type
All data types are listed under the default mode There is a checkbox “□“ ahead of the data type, which is used to control whether display the layers belongs to this data type or not. Mark √ in the box represents current layer will be displayed, Click on □ to switch between the selected status and unselected status.
Layer
Each specific display data is a layer, except for well layers. All Well data are grouped into one layer. Layers are not initially displayed on the Data Explorer Tree after basemap is started - users can select the layers to be displayed by selecting Layer Display from the Layers menu. Display layers are listed under their corresponding data types with checkbox display switches. Layers are arranged on the data tree in the same display order as the Display Window from the top layer to the bottom layer. Users can adjust the display order of the layers through layer display.
Ex(Extend)
The Extend column lists the extended information of the data, for example, 3 is listed after surveys indicating that it is a 3D survey, and the survey name is listed after the horizon.
The Blank Area of the Data Explorer Tree
The right-click menus related to data types and layer data are set on the Data Explorer Tree. Through these menus, the layer to be displayed can be selected, the current layer can be activated, the display order of the layer can be set, and
the display parameters of layer properties can be set. The right-click menu related to the Data Explorer Tree can be divided into three types: the blank right-click menu, the data type right-click menu and the layer right-click menu.

Multiple Attributes Fusion
Multiple attributes fusion display means to select two or more seismic attribute data, and fuse their corresponding values according to a certain calculation rule to form a new color map, which is used to highlight the geological meanings of seismic attributes and then facilitate interpreters to analyze.
There are three fusion display modes:
Tri-attribute RGB Fusion display mode
Based on seismic attribute analysis, select three seismic attributes (specifically, three single-frequency amplitude attributes) which don't overlap each other. After attributes normalization, each attribute respectively corresponds to the color of red, green, and blue, then fuse them in the mode of RGB to form a new color map. Such 3-attribute RGB color fusion enables the user to obtain more geological information.
Bi-attribute 2D colormap fusion display mode
Select two data that respectively correspond to the X-axis and Y-axis of 2D colormap, fuse these two attribute data with 2D colormap to enhance the visual effect and interpretability of seismic data, and improve the interpretation precision.
Multiple attributes color ratio fusion display mode
Select multiple attribute data volumes (4 at most), each of which corresponds to a colormap, fuse each attribute data with its colorbar at a certain ratio to generate a colorbar for every point. The sum of attribute ratios shall be equal to 1. This mode facilitates the contrast analysis of multiple attributes.

Color Block Data Cartogram:
At the top of and on the right side of the dialog respectively show X-axis and Y- axis color block data cartograms. These cartograms indicate distribution sample points corresponding to each color block. When the range, color number, and value- color mapping are changed, the cartogram will make a statistical analysis again. The
color of the cartogram can be changed by clicking on the Statistics color button.
Color Number Setting:
The number of colors of the X-axis and Y-axis colormaps may be set by using "X color num" and "Y color num" dropdown lists or by manually entering. (Note: only odd numbers are valid).
Label Precision Setting for the Color Stick:
If the label precision is not set, the system will automatically calculate data precision (keeping decimal digit after the decimal point); in addition, it will displayed data in scientific notation when data is very large. If the label precision is set, all color sticks associated with the colormap will be displayed in the user-set precision. Setting method: select the Precision check box and then click the triangles or directly input a numeral value.
Set Data Value Range:
The user inputs the data range in “Interest Range” and sets the range corresponding with the colormap by clicking the Set button. The data within the data range will correspond with the corresponding color in the colormap. Stipulation: when the value of the data is less than the minimum in the range, the first color is gotten; when the value of the data is larger than the maximum in the range, the last color is gotten.
Click the Reset button to restore the initially set data range (the initial range is the maximum and minimum values of the current section of selected data).
The range can also be adjusted by dragging the mouse below the color stick, as shown in Figure 5.16-6.

Next, the traverse picking methods mentioned above would be described in detail.
Free traverse
Once free traverse picking is selected, freewill multi-segment would be picked.
The regular rules for picking are left-clicked for picking, middle-click for cancel, right-click for context menu and double-click to end picking. After a traverse is finished, the new traverse would be ready to be picked automatically.
We can pick a traverse under the 2D survey /3D survey/ combined survey. In the process of picking, any segment has to be limited to a single survey. If the traverse has to cross surveys, users could apply “M” to adjust the survey order. The survey must be the topmost layer in the stacked display area in a combined survey. If the picking action is transferred from the 3D survey to the 2D survey, end the 3D survey traverse segment and begin
picking in the 2D survey; and if the picking action is transferred from the 2D survey to the 3D survey, end the 2D survey traverse segment and begin next picking in the 3D survey.
Pick traverse under 3D survey.
If the cursor moves by the line, the line would be highlighted in the defined color. Users could finish the following operations by mouse:
Left click Left-click in the Display Window would lead to picking a new point, if the picking position is outside the survey area, the picking point is invalid. In the case that the picking point is available, use the mouse plus Ctrl (MB1+Ctrl) to snap the picking point to Inline/Crossline. In principle, the picking line is snapped to the line with a smaller included angle; double left-clicks to end picking; left-click with keeping “W” down would snap the picking point to well. If the picked traverse has intersected with wells, keeping “W” down would also snap the picking segment to well.
Middle click: Middle-click on the point continuously would perform the multi- point deletion.
Right click: Right-click to activate the content menu of traverse picking, and users can select other traverse types from the context menu and delete the original traverse, as shown in Figure 6.4-2.
Pick traverse under 2D survey
If the cursor moves by the line, the line would be highlighted in the defined color.
Left click on the line to pick a new point, if the picking point is on a line intersecting that of the previous point, it will automatically snap to the intersection point. Middle-click on a point would delete it, which can be used successively to delete several picking points. Double left-click to end the picking. Right-click and a right-click menu of Pick Traverse will appear, as shown in Figure 6.4-2. The menu operation is the same as that of the 3D survey. if the picking point is not on the line, a warning window as Figure 6.4- 5 will appear;
Pick traverse under a combined survey
When picked points of the traverse are located in the area occupied with a single survey, the operation mode is the same as that for a single survey. If picked points of the traverse are located in the area occupied with the combined survey, the picking would occur in the topmost survey on the data
tree. The topmost survey is also set the priority by users from the context menu. For example., if the picking is transferred from single survey A to combined survey B, it is required to set survey A prioritized, on purposing of combine survey picking.
Rectangle traverse
In the 3D survey grid, left-click and drag the left button to create a rectangle in the Inline/Crossline direction. Release the left button to define a rectangle composed of corresponding inline and crossline. If the user defines a new rectangle, the previous rectangle will disappear. The basemap only retains the last rectangle. users can select other traverse types from the context menu and delete the original traverse, as shown in Figure 6.4-2.
Polygon traverse
In the 3D survey grid, left-click to pick the inflection point, middle-click to return, and double-left-click to end the polygon picking. The basemap only retains the last polygon. Users can select other traverse types from the context menu and delete the original traverse, as shown in Figure 6.4-2.
Across traverse
The across traverse must be picked in the Inline/Crossline direction under the 3D survey. Left-click at the desired position in the survey grid will create a set of across traverses in Inline/Crossline direction with the clicking point as the crossing point. Left click again, the previous set of across traverses will disappear, and instead, a new set of across traverses will appear. Users can select other traverse types from the context menu and delete the original traverse, as shown in Figure 6.4-2.
Pivotal traverse
In the 3D survey grid, users can create a serial of pivotal traverses between two segments, each of which consists of two points. Left click in the Display Window to pick the point. After picking two points, the traverse is confirmed under two endpoints. Pick the ending traverse by the above-mentioned method; where middle click to return to the previous picking point. After the ending traverse picking is completed, the dialog shown in Figure 6.4-6 will appear.
Figure 6.4-6
Input the number of infill traverses in the dialog and click OK. The line segments will automatically insert between the start and end traverses. Users can select other traverse types from the context menu and delete the original traverse, as shown in Figure 6.4-2.

Delete Segment
Segments can be deleted repeatedly until users select other functions from the function menu. Users have to activate segments by left-clicking on them before segment deletion.
If the activated segment is unclosed, picking two points on the segment by left- clicking, the partial segment between two pints would be eliminated.
Otherwise, two points are determined at the segment-first, and the third point is selected by the mouse. If the last point is located between the first two points, the partial segment limited by the first two points is cleared. In the case of the third point exceeded the two points, the partial segment outside of the first two points would be eliminated.
Move Segment
Segments can be moved repeatedly until users select other functions from the function menu. Keep the left button down and drag the segment, moving segment would happen when the mouse is released at the appropriate location.
Copy a Segment
Select a segment and left click on the target location, a duplication would be generated here and enter the pick mode meanwhile as long as the operation is performed once.
Break a Segment
Select a segment and its inflection points are therewith displayed. Left-clicking on an inflection point would result in the segment break gapped with a distance of 50 meters.
Pick mode is in meanwhile, as long as the operation is performed once.
Link
It is capable of linking two segments together, except that a segment is closed and the other is unclosed. The linking of two-segment with the same type will work as follows:
1、 Linking two unclosed segments
Clicking on the first segment and the endpoint near the clicking position would be thickening. And then clicking on the second segment and the endpoint near the clicking position would be thickening too. Meanwhile, the two endpoints would be jointed together. Taking Figure 6.8-14 as an example, the endpoints 1 and 2 are connected as illustrated in Figure 6.8-15.

Set Downthrow Side
Users can set downthrow side repeatedly until they select other functions from the function menu.
1、Set selected segment as downthrow side
If the selected polygon is unclosed, use the mouse to select a node as a start point and another node as the endpoint, the segment between the two points is defined as downthrow side and displayed based on display parameter of the downthrow side.
If the selected polygon is closed, use the mouse to select a node as a start point and another node as the endpoint, and then select the third point as the direction, the segment among the three points is defined as downthrow side, and
displayed based on the display parameter of the downthrow side.
2、Set selected segment as upthrow side
If the selected polygon is unclosed, left click to select a node as a start point and middle-click to select another node as the endpoint, the segment between the two points is defined as upthrow side and displayed based on display parameter of the upthrow side.
If the selected polygon is closed, use the mouse to select a node as a start point and another node as the endpoint, and then middle click to select the third point as the direction, the segment among the three points is defined as upthrow side, and displayed based on display parameter of the upthrow side.
After the definition is completed, return to the Pick mode.

GeoBasemap Communication
Line Selection
To switch the basemap to line selection mode, the Basemap must be started and the survey is displayed on it. When the basemap line selecting result is related to a section interpretation window (that is, the profile displayed in the section interpretation window is along the selected line), the Basemap will automatically clear the corresponding line if the section interpretation window is closed.
Two modes exist for starting Basemap line selection:
Starting Basemap Line Selection from Other Applications
The basemap can accept requires being in line selection mode from other applications.
Inline/Crossline Selection
1、Selection
If the only 3D survey is present on the basemap, Inline/Crossline selection would be available to start the section interpretation window. Right-clicking pops up a context menu shown in Figure 7.1-1.
Figure 7.1-1
where：
Inline Selecting Inline items would offer access to inline selection mode. Move the mouse in the survey and click on it at the satisfying location to determine an inline line, the selected line would turn into red (or other color defined) and is sent to the application subsystem which is required to employ the selected line. In the case of wells displayed in the 3D survey, the well turns into another color while the mouse goes by the well location. It also offers a shortcut to quickly select the line intersecting with a well through keeping w down and left-click.
Crossline Selecting items would offer access to Crossline selection mode. Move the mouse in the survey and click on it at the satisfying location to determine the line, the selected line would turn into red (or other color defined) and is sent to the application subsystem which is required to employ the selected line. In the case of wells displayed in the 3D survey, the well turns into another color while the mouse goes by the well location. It also offers a shortcut to quickly select the line intersecting with a well through keeping w down and left-click.
Display It is only active under the condition of keeping Ctrl down to select several lines meanwhile. Once it is doable, operation with the item is capable of sending multiple lines simultaneously.
Exit Exit the line selection mode.
2、Display the section along selected lines
After Basemap start-up, the corresponding line along which any section(except for slices) in conventional interpretation is displayed is allowed to show on the basemap: the single section as a single line, the folded section as two intersecting lines (Inline, Crossline), and the multi-line section as all the lines included in it. The following edit options are available in basemap:
Draglines: if the survey which contains the selected line has been activated and the user has exited the line selection mode, moving the cursor to select the desired line on the basemap changes the cursor to a hand shape. On left clicking, the line will thicken, indicating that the line has been selected. Click and hold the left button, the selected line will move with the cursor. Release the left button, the originally selected line will move to the position where the mouse is released, and the line will automatically be sent to the application system corresponding to the originally selected line. The line will be restored.
Note: Users can only select one line related to a multiple-line section interpretation
window to drag and meanwhile other lines in basemap would be removed with the drag operation.
Switching line: Under no line-selection mode without active selecting icons in the toolbar, move the cursor to the selected line on the basemap and the cursor will become hand shape. Left-click to select the line and the line will be sent to the application window. Right-click to pop up the right-click menu shown in Figure 7.1-2, users can select lines again with it.

Where:
Inline Select this option to enter the Inline selection state. After selecting the Inline line, send the currently selected line to the application window that made the line selection request, and the basemap will exit the line selection state
Crossline Select this option to enter the Crossline selection status. After the Crossline line is selected, the currently selected line is sent to the application window that made the line selection request, and the basemap exits the Crossline selection state.
Display Sent the selected multiple lines to the applicant. It is only selectable when pressing Ctrl to select multiple lines.
Exit Exit the line selection mode.
Selecting 2D survey Line
When the 2D survey is displayed in the basemap, users can enter the 2DLine selection mode. The 2D line will become red or the other colors defined by the user when the cursor goes through it. Left-click to select the line, using Ctrl plus the left mouse button can select multiple 2D lines, and right-click to pop up a context menu, as shown in Figure 7.1-3.

Exit Exit the line selection mode.
Selecting Inline/Crossline or 2D Line
When 2D survey and 3D survey co-exist on the basemap, either mouse location or the survey order is feasible of being a reference of line selection. The line would be highlighted and turn into red (or other defined color) once the moving mouse goes by the line. Multiple clicks with keeping Ctrl down result in selected multiple lines. Right-click brings out a context menu as shown in Figure 7.1-4.
Figure 7.1-4
where：
Inline/2D Line Selecting this item would offer access to the
inline/2D line selection mode. After the operation, the selected line would be sent to the applicant meanwhile the basemap is going to leave the line selecting status. In the case of wells displayed in the current 3D survey, the well turns into another color while the mouse goes by the well location. It also offers a shortcut to quickly select the inline line intersecting with a well through keeping w down and left-click.
Crossline/2D Line Selecting this item would offer access to
Crossline/2D line selection mode. After the operation, the selected line would be sent to the applicant meanwhile the basemap is going to leave the crossline selecting status. In the case of wells displayed in the current 3D survey, the well turns into another color while the mouse goes by the well
location. It also offers a shortcut to quickly select the inline line intersecting with a well through keeping w down and left-click.
Display It is only active under the condition of keeping Ctrl down to select several lines meanwhile. Once it is doable, operation with the item is capable of sending multiple lines simultaneously.
Exit Exit the line selection mode.
Selecting Traverse
Once another application selects the function icon for picking a traverse from the basemap, the basemap will enter the traverse-picking mode. Here are some hints:
When a new traverse is picked, the current displayed traverse on the basemap is retained in green for now.
In the process of traverse picking, the old traverse is reserved.
New traverse will send to the corresponding applicaiton for displaying after finishing the traverse picking.
The old traverse would disappear as long as the display is performed and the new traverse would be kept.
In case of display failure, the old traverse would be kept with the original color and the new traverse would disappear.
If the new traverse is saved first instead of sent to the applicant, it will replace the old green traverse.
In the traverse picking mode, Right-clicking would bring out a context menu shown in Figure 7.1-5 empowering users to switch traverse types optionally.
When there is a corresponding unnamed traverse path in the seismic interpretation window, then enter into the traverse picking mode from the interpretation window, the original path will be in green and the newly picked traverses are in red. In the right-click menu, select Cancel to cancel the red track and restore the green track.
Select Display in the right-click menu, and send the traverse to the applicant Please refer to section 6.4.9 Select Traverse for details of picking traverses.
Basemap Selecting Line Autonomously
This function applies only to Inline/CrossLine/2Dline. Select the desired line type from the basemap toolbar, line selection mode is activated.
Select a line and activate a section interpretation window, if a section
interpretation window is already open (if not, start the conventional interpretation application).
Traverse Scrolling Display
A traverse scrolling display is available as the section interpretation window displays the profile along a traverse. Meanwhile, the traverse scrolling display would be refreshed on the basemap and be saved with the a series of names as “UnNamedTra***” under the traverse node on the data tree.
Basemap Cursor Communication
Other applications could send the cursor position to the basemap application; the basemap receives and displays the position of the geodetic coordinate corresponding to the other application in the shape of the cross cursor.
Horizon Communication
Horizon communication in the basemap refers to communicating with the
GeoSeismic subsystem.
To perform horizon communication in the basemap, both the basemap and the section interpretation window must be opened, and the same horizon should be displayed in the basemap and the section interpretation window at the same time.
Horizon communication in the basemap mainly includes the following cases: horizon picking display, horizon deleting, and saving, descriptions are as follows:
Horizon Picking Display
Pick horizon in the section interpretation window, and the achievement can be displayed in the basemap in real-time. And the horizon value range after the horizon is chosen is calculated in real-time, if the value range changes, the value range and colormap range in the parameter interface will be updated in the basemap.
Horizon Deleting
If the section interpretation window is in horizon interpretation mode, select Delete Part or Delete Lines from the right-click menu to delete horizons, and the horizons deleted from the section interpretation window will be removed from the basemap in real-time. And the horizon value range after the horizon is deleted is calculated in real-time, if the value range changes, the value range and colormap
range in the parameter interface will be updated in the basemap.
Horizon Saving
After the deleting operations of the horizon area or of the horizon inside the fault polygon are performed in the basemap, select save To DB from the right- click menu to save them to the database, the horizon deleted from the basemap will be also deleted from the section interpretation window.
Fault Communication
Fault communication in the basemap refers to communicating with the
GeoSeismic subsystem.
To perform horizon communication in the basemap, both the basemap and the section interpretation window must be opened, and the same fault should be displayed in the basemap and the section interpretation window at the same time.
Fault communication in the basemap mainly includes the following cases: fault picking display, fault deleting and saving, and descriptions are as follows:
Fault Picking Display
Pick faults in the section interpretation window of GeoSeismic subsystem, and the picking results can be displayed in the basemap in real-time.
Fault Deleting
If the section interpretation window is in fault interpretation mode, select Delete from the right-click menu to delete faults, and the faults deleted from the section interpretation window will be removed from the basemap in real-time.
Fault Saving
After the deleting operations of the fault in the display area of GeoBasemap, select save To DB from the right-click menu to save them to the database, then the fault deleted from the basemap will be also deleted from the conventional interpretation subsystem GeoSeismic.
Communicating with GeoAttribute Subsystem
